Make sure you can do as many topics as possible in your foundation or higher syllabus.

Topic questions can be asked in different ways, leading to different levels of difficulty. So practise ‘thinking on your feet’, working out what the question is about before answering them.

For example, the Hannah’s sweets question (2015 Edexcel Maths GCSE paper), is a probability tree question with some algebraic rearrangement. See if you can work it out.

There are n sweets in a bag. 6 of the sweets are orange. The rest of the sweets are yellow. Hannah takes a random sweet from the bag. She eats the sweet. Hannah then takes at random another sweet from the bag. She eats the sweet. The probability that Hannah eats two orange sweets is 1/3.
